Tuning connection-related parameters

In this recipe, we will talk about tuning the connection-related server parameters.

How to do it...

The following are the connection-related parameters that usually require tuning:

• listen_addresses

• port

• max_connections

• superuser_reserved_connections

• unix_socket_directory

• unix_socket_permissions

These parameters can be set to appropriate values in the postgresql.conf file and these parameter can be set at server start. The changes made to these parameters will only come into effect once the PostgreSQL server is restarted, either using the restart mode of the pg_ctl command or using the stop mode and then followed by the start mode of the pg_ctl command. This can be done as follows:

pg_ctl -D $PGDATA restart

Here, $PGDATA refers to the environment variable that refers to the data directory location of the PostgreSQL server.

How it works...

Here, we will talk about the connection-related parameters discussed in the preceding section:
